I have no experience on these old Mopar hinges but I have restored numerous Muscle car era door hinges using bronze bushing to bring the hinges back to life and they have held up very well. I also believe there is quite a bit of weight in the modern car door once they started adding the crash beam inside the doors along with all the power operated features. You would be surprised on how heavy these later era door are compared to these old Mopars. Have you ever removed a door from a 1974 Grand Prix, if you have you know what I’m talking about. It’s a 2 man job, compared to my 49 Wayfarer Convertible door that I can install by myself.
